Self-adaptation frequency hopping pattern generation method

The invention discloses a self-adaptation frequency hopping pattern generation method. Both parties of communication obtain the same SNR and the same SIR through channel estimation, an adjustment factor Vt of a frequency hopping pattern is generated, an operation is performed on the adjustment factor Vt and a frequency hopping pattern control word rt generated by a pseudorandom sequence generator to obtain a frequency hopping pattern control word t, and the frequency hopping pattern control word t is used for generating the frequency hopping pattern. In the self-adaptation frequency hopping pattern generation method, channel estimation is used for generating the self-adaptation frequency hopping pattern based on channel dynamism, the channel dynamism utilized by the self-adaptation frequency hopping pattern is the special characteristic of the both parties of communication, any third party cannot copy the characteristic, and the interception resisting performance is further improved. More importantly, even if one device is cracked or obtained by the enemy, effective interception and interference cannot be performed.
